Train axle detection alignment device

Abstract

A train axle detection alignment device belongs to the field of auxiliary alignment devices for acceptance and detection of railway train axles of different lengths. The train axle detection alignmentdevice includes a longitudinal double-guide-rail base, two vertical props, two axle radial positioning seats, a cam cylinder and a base slide thereof, a double-link alignment mechanism based on a camturntable, two axle end tightening mechanisms, a gear box support mechanism and a displacement detection mechanism. The two axle end tightening mechanisms of the invention can synchronously and reversely transfer the driving force of the double-link alignment mechanism, an alignment roll pressure head can apply the driving force to the end of an axle, and a traction rod shaft can apply the driving force to a ranging piston rod. Thus, a ranging piston cylinder on the displacement detection mechanism can measure the displacement along the oblique direction as a driven part, the rough value of the horizontal displacement component at the axle end can be obtained by calculation, and the axle length type corresponding to the axle currently being detected can be judged according to the axle length interval corresponding to the rough value of the horizontal displacement component.

Description

technical field [0001] The invention belongs to the field of auxiliary centering devices for the acceptance and detection of rail train axles of different lengths, and in particular relates to a detection and centering device for train axles. Background technique [0002] The axle of the rail train is a stepped axle with a large size. Since the axle itself must have a length dimension error L1 and a radial machining error during processing, it is necessary to carry out dimensional inspection and acceptance of the finished product after processing. [0003] Such as Figure 1 to Figure 3 Shown rail car axle 9 with gear box, the left and right sides of its main shaft section are respectively provided with a section shaft diameter 9-1, and gear box 10 is coaxially fixed on the outer diameter of main shaft section, and the outer diameter of gear box 10 The diameter is fixedly connected with gear case mount 10-1. When carrying out quality acceptance testing after machining such a...

Problems solved by technology

[0007] In order to solve the problem that the equipment used in the existing laser centering instrument detection method is expensive, and requires a high level of operator's operating skills, it is difficult to popularize, and the conventional manual length measurement method is not only inefficient, but also caused by human error and other factors. Poor, according to the manual measurement of the length of the axle to judge the technical problem of the axle type measurement operation is prone to misjudgment, the invention provides a train axle detection centering device
